IMPRQVE MENT IN HAND-LO OMS Specification forming part of Letters PatentNo. 169.098., dated October 26, 1875 application filed June 24,1875; 1

To all whom it may concern:

'Be it known that I, JAMES E. GILLESPIE, of Boston, in the county ofSuffolk and State of Massachusetts, have invented Improvements inHand-Looms, of which the following is a specification:

This invention relates to improvements in hand-looms, and is speciallyadapted to such looms as are employed to weave duck and heavy fabrics,hose, &c., in which it is necessary to beat up the weft very close andhard to make a strong, dense, solid fabric; and the invention consistsin means for throwing the lay forward, or to assist the operator inthrowing it forward, as hereinafter described.

A cord, band, or rod extends from the front to the back of the loom, andbetween two friction-rollers carried by the lay, one of which ispositively and constantly rotated, and the other of which is mounted onan arm projecting from a part of the hand-rail or other part of the lay,and when the two rollers are forced toward each other, so as to pinch orbind the cord or hand, then the positively rotated wheel will, by itscontact with the cord or band, move along the same and cause the lay tobe thrown forward quickly and forcibly.

Figure l is a front view, and Fig. 2 is a side View, of a loom providedwith my improvement; and Figs. 3 and 4 are modifications.

A denotes the frame of a loom, of any wellknown or suitableconstruction. The lay ahas its swords pivoted on the rod or shaft 1),lesting in bearings in one of the cross-pieces of the loom, and the laycarries a reed, c. Harness-frames d are suspended from pulleys on shaft6, and are raised and lowered by pressure on the treadles f. A shaft, g,extends across the lay under the race-hoard, and at each end carries agrooved pulley and a bandpulley, i, the latter being connected by bandsor belts] with pulleys 70 on the shaft 1), which forms the pivotalcenter of the lay, which shaft is driven by power while the loom is inoperation. Extending from the back to the front of the loom at each sideis acord, 1, and it bears on the grooved pulley h.

w of the lay is a hand-rail, m, whose side pieces m are pivoted at a tothe lay-sword or racebeam, and an arm projecting laterally there- At thetop A spring, 1;,

the degree of pressure applied to the bandv and the speed of the wheelh. The cord or band may be'adjusted to be more or less taut. Uprights q,attached to the lay and provided with regulating-screws r, govern theback movement of the top rail, while the backward position of the lay isregulated by the stops s. Adjustable stop-pieces t on the loom-framegovern the torward'throw of the lay, Such stops, acting against thehand-rail side pieces, or against adjustable projections thereon, turnthe hand-rail on its pivot-pin, disengaging the hold of thefriction-wheel on the cord or band, and stopping the further movement ofthe lay forward.

In weaving hydraulic-hose fabric, where it is necessary to beat in thefilling very closely, the lay is usually weighted to assist the operatorin striking a hard blow, and each Weft is usually beat in several times,and this class of weaving requires the expenditure of much strength, andthis class of hand-looms is commonly operated by men. By these mydevices the operator has only to throw the frictionpulley carried by thehand-rail frame in contact with the other pulley, and by exerting moreor less force on the long arm m of the hand-rail, which may beconsidered as a lever, the friction-pulley of the short arm will bindbetween it and the driven pulley h. the band or cord allowing less ormore slip between the cord or band and pulley, and consequently theforce of the blow may be easily governed. Movement forward of the top ofthe hand-rail causes the lay to beat up.

This hand-rail might'he controlled through a treadt: at the lower partof the loom. Any other well-known harness-motion than that described maybe used.

Instead of stttioniaai cord or belt I might usea movable belt, as shownin Fig. 3,

the arrow showing the direction of its-movement, and when thefriction-roller is depressed on t W l er: wi lzbe th ow q a s -t In Fig.4, instead of fleqrible nd or c 7 I employ a. rod, u;c0nnctedwitha'"edii'is bar, 12, which is reciprocated through a. crank and link, andwhen the friction roller or wheel is depressed against the rod the mywinbe moved.

I. The I friction-pulley, and driven pulley with a band,

enlistment)? an 155", its mantle cord; or rod; whereby thelaymaywbethrown forward, substantially as described.

2. The combination of the lay, its pivoted hand-mil, and friction-pulleywith a, stop to l meet the handrail and disengage the frictionpnl lejfrorn the tliefl i'rwlrd position of thelay; substantially as described.In testimony whereofl have signed my name to this specification in thepresence of two subso ribiiig witnesses.
